Gliese 892 is the seventh nearest G-type star. At V = 5.5, it's visible to the naked eye. It was one of the targets of the first-ever radial velocity planet seach. It's not a well-known star, but it sure will be after this.

I do not know much English, so I will say that the slides are taken from video of the conference.

They wouldn't bother announcing it if the publication wasn't ready, I imagine.

I haven't got to the part of the conference where they talk about the system yet, but inspecting the slides, it looks like there are 5 planets, not 6. I think the 1190-day signal in the first slide is the same as the 2334-day signal in the second, but the first is based on less data (only APF, I imagine)(Actually, that's HARPS-N).

(Deadit: Hm. The person advertising the Keck+APF poster says 6 planets, but the picture only shows 5 signals. Not sure how to interpret that…)

(Breadit: I finally got to the poster. The sixth signal is a candidate at 94 days. The long-period signal is possibly magnetic.)

I meant in past I saw similar slides from conference 2 years ago about 61 virginis (at least 5 planets system) like this one about gl 892 and still they did not make any announcement about new planets around 61 virgo so I am not so sure about any quick announcement about gl 892

Um, Wow! HARPS-N + Spitzer team up to give us a transiting rocky super-Earth around a naked-eye star. This is going to become a *very* well-studied planet (Three more planets were also found, making this a four-planet system).

As regards the question of the two additional planets, see the end of the paper:

Note added in proof. During the refereeing process, we learned about an independent detection by Vogt et al. (Laughlin, private communication) reporting additional planets in the system, based on long-term radial velocities obtained with the Keck and APF telescopes.

So presumably there's (at least) another paper to come regarding this system...
